The PDF version is not in the "info" object or the PDF metadata. I don't think it's accessible from the IAC either.

The only place you can find the PDF version is in the first 9 bytes of the PDF file. Fortunately there is an undocumented JS method that provides access to the binary file data.

var stmDoc = Collab.documentToStream(this);

var pdfVer = util.stringFromStream(stmDoc).substr(5,3);
